With the arrival of 
Ubuntu 10.10, the list of reasons to try 
Linux  for your 
business just got a little longer. The free and 
open source  operating system is now more user-friendly than it's ever been before  while still offering the many 
security and other advantages it has over its competitors. If  you're among the legions of new Linux users out there, congratulations  on making a smart move! Now that you're on your way to a lifetime of  freedom from high costs, vendor lock-in, constant malware attacks, and  the many other disadvantages associated with 
Windows and 
Mac OS X, you  should be aware of some of the classic mistakes Linux newcomers  sometimes make.
None of these should be deal-breakers, by any  means. Nevertheless, an early heads-up can help prevent unnecessary  frustration. Without further ado, here are five key things you should  avoid when starting out with desktop Linux.
1. Expecting WindowsHumans are creatures of habit, so after years of using Windows--or Mac, if that's the case--it's hard not to expect what you're used to every time you use a computer.
Ubuntu and recent 
Linux distributions  have incorporated many user-friendliness features from their Windows  and Mac competitors in recent years, so there is actually going to be  quite a bit of similarity these days--much more than there used to be.  When it comes right down to it, though, even consumer-ready Maverick  Meerkat isn't Windows, and you shouldn't expect it to be.
This is not--I repeat, NOT--to say that things are harder. Linux is not more difficult  to use, especially if you're on a modern distro like Ubuntu. It is,  however, different. It might take you a little bit of time to get used  to its slightly different way of doing things. Don't let that put you off--a small learning curve will gain you a lifetime of advantages.
2. Running as Root UnnecessarilyOne of the big  differences between Linux and Windows is that Linux users don't  typically have "root," or administrator, access. That's a very good  thing for security, and it's something you should take care to preserve  by not running as root unnecessarily.
That said, you should not  fear running as root, either. There are some tasks that require root  privileges, and for good reason. Just make sure you do it only when  necessary.
3. Using Google to Find SoftwareIf  you're coming to Linux from Windows, for example, you're used to the  hunt-and-peck approach to finding new 
software packages online--and  then, doubtless, paying dearly for them. One of the beauties of Linux,  however, is that it makes this process much easier--not to mention  generally free.
Most every Linux distribution has a package manager, and that's one of the first things you need to find. In Ubuntu, it's the Ubuntu Software Center,  and it is your friend. With the package manager, you'll be able to find  just about any software you need, and probably for free.
4. Fearing the Command LineIt's  a testament to how far Linux--and operating systems in general--have  come that many people have never had to use a command line. With  distributions like Ubuntu Maverick Meerkat, you still won't have to, for  most purposes.
Don't live in fear of the command line, though.  It's no more difficult to type in a few short commands than it is to  click through the necessary screens in a GUI, and it can be both faster  and more effective. I'm not saying you need to seek it out, necessarily,  but if something comes up that requires it, don't stress out.
5. Giving Up Too EasilyChange  can be hard, no matter how simple the technology you're changing to  might actually be. It's important to remember that you weren't born  knowing how to run Windows or OS X, either--you had to learn and get  used to it.
Same goes with Linux. It might feel a little  different from what you're used to, but that doesn't mean it's hard or  bad--it's just different. Stick with it just a little longer, though,  and you'll soon stop noticing the areas where it's different from  Windows or Mac. Stay a little longer, and you'll start seeing that many  of the ways Linux does things actually make more sense. After that, it  won't be long before you can't imagine going back.
